A box plot is a graphical representation of five numbers. Working from left to right the first line is the lowest value in the data set, the second line (the start of the box) is the lower quartile, the third line (the line inside the box) is the median, the fourth line is the upper quartile and the fifth line is the highest value. The width of the box represents the interquartile range and the distance between the two outer lines represents the range. That's it.

15. One final thing that wasn't mentioned, outliers... They're pieces of data that don't fit the data range because they're extreme.

Worked out by:

Lower quartile - 1.5(interquartile range)
Upper quartile + 1.5(interquartile range)

They're not drawn on but marked by a cross where they would have been.

There are a number of ways of working out outliers - this is just one
